[patch, committed] libxfce4util memleaks

[Brian J. Tarricone]

hey all-
i was tracking down some memleaks in xfdesktop, and valgrind found 3 
leaks in the new XfceDesktopEntry code, totalling around 350k or so with 
my usage.  the patch was relatively trivial, so i went ahead and 
committed it.  it's just to 
libxfce4util/libxfce4util/xfce_desktop_entry.c, bumping it to rev 1.6 on 
HEAD.

hope i'm not stepping on any toes, the patch is in 
http://kelnos.homelinux.org/xfce4/ if anyone needs/wants to look at it.
